Question

On a unit circle, the terminal point of 0 is (0, -1). What is tan 0?

Answer 1

Answer:

Undefined

$\tan \theta=\text{ undefined}$

Explanation:

Given that the terminal point on a unit circle is at;

$(0,-1)$

Recall that from trigonometry tangent is;

$\tan \theta=\frac{opposite}{adjacent}=\frac{y}{x}=\frac{-1}{0}$

and we know that any number divided by zero is undefined.

Therefore;

$\tan \theta=\text{ undefined}$

tan theta = undefined
